Proof Ange, marquis Luiggi-Giafferi was the son of Stefano Canzio please?
I was trying to establish a relationship with Ange & his proposed wife Jeanne Hadot for whom there are also no primary sources. It is not even clear she was a child of the Hadots she is connected to here as they married later in life, and I have not been able to find any record of them having children.
I think what may have happened again is people have copied in trees from Ancestry, MyHeritage, etc without sources and there are several mistakes throughout these lines.
I have found a Corsican Prime Minister Luigi-Giafferi, and he may have had a son. The problem here is while this Prime Minister Luigi-Giafferi was born in France and passed away in Italy, he lived from 1668-1748. So if he was the father of Ange, then his Ange was not married to someone born after 1904, which is when the proposed parents of Ange Luigi-Giafferi's "wife" here on Geni married.
Any sources backing up the links or other thoughts/suggestions welcome!
